|

|
||||
<h2><a name="overview">Overview</a></h2>
|
||||
|
||||
<p><tt>nss-myhostname</tt> is a plugin for the GNU Name Service Switch
|
||||
(NSS) functionality of the GNU C Library (<tt>glibc</tt>) providing
|
||||
host name resolution for the locally configured system hostname as
|
||||
returned by <tt>gethostname(2)</tt>. A lot of software relies on that the
|
||||
local host name is resolvable via DNS to an IPv4 or IPv6 address. When
|
||||
using dynamic hostnames this is usually achieved by
|
||||
patching <tt>/etc/hosts</tt> which however is suboptimal since it
|
||||
requires a writable <tt>/etc</tt> file system and is fragile because
|
||||
the file might also be edited by the
|
||||
administrator. <tt>nss-myhostname</tt> simply returns the IPv4
|
||||
address <tt>127.0.0.2</tt> (wich is on the local loopback) and the
|
||||
IPv6 address <tt>::1</tt> (which is the local host) for whatever
|
||||
system hostname is configured locally. Patching <tt>/etc/hostname</tt> is thus no longer necessary.</p>
|
||||
|
||||
<h2><a name="status">Current Status</a></h2>
|
||||
|
||||
<p>It works!</p>
|
||||
|
||||
<h2><a name="documentation">Documentation</a></h2>
|
||||
|
||||
<p>After compiling and installing <tt>nss-myhostname</tt> you'll find a
|
||||
new NSS modules in <tt>/lib</tt>:</p>
|
||||
<ul>
|
||||
<li><tt>libnss_myhostname.so.2</tt></li>
|
||||
</ul>
|
||||
|
||||
<p>To activate the NSS modules you have to edit
|
||||
<tt>/etc/nsswitch.conf</tt> and add <tt>myhostname</tt> to the
|
||||
line starting with "<tt>hosts:</tt>". On Debian this looks like
|
||||
this:</p>
|
||||
|
||||
<pre># /etc/nsswitch.conf
|
||||
|
||||
passwd: compat
|
||||
group: compat
|
||||
shadow: compat
|
||||
|
||||
hosts: files dns <b>myhostname</b>
|
||||
networks: files
|
||||
|
||||
protocols: db files
|
||||
services: db files
|
||||
ethers: db files
|
||||
rpc: db files
|
||||
|
||||
netgroup: nis</pre>
|
||||
|
||||
<p>That's it. You should now always be able to resolve your local
|
||||
system hostname. For a quick check
|
||||
use <tt>glibc</tt>'s <tt>getent</tt> tool:
|
||||
|
||||
<pre>$ getent ahosts `hostname`
|
||||
::1 STREAM omega
|
||||
::1 DGRAM
|
||||
::1 RAW
|
||||
127.0.0.2 STREAM
|
||||
127.0.0.2 DGRAM
|
||||
127.0.0.2 RAW
|
||||
</pre>
|
||||
|
||||
<p>In this case the local host name is <i>omega</i>.</p>
|
||||
|
||||
<p>It is recommended to put <tt>myhostname</tt> last in
|
||||
the <tt>nsswitch.conf</tt> line to make sure that this mapping is only
|
||||
used as fallback, and any DNS or <tt>/etc/hosts</tt> based mapping takes
|
||||
precedence.</p>
|
||||
|
||||
<h2><a name="requirements">Requirements</a></h2>
|
||||
|
||||
<p><tt>nss-myhostname</tt> uses NSS interfaces that are specific to modern <tt>glibc</tt>'s.</p>
|
||||
|
||||
<p><tt>nss-myhostname</tt> was developed and tested on Fedora 10
|
||||
from October 2008, it should work on most other Linux
|
||||
distributions since it uses GNU autoconf and
|
||||
GNU libtool for source code configuration and shared library
|
||||
management.</p>
|
||||
|
||||
<h2><a name="installation">Installation</a></h2>
|
||||
|
||||
<p>As this package is made with the GNU autotools you should run
|
||||
<tt>./configure</tt> inside the distribution directory for configuring
|
||||
the source tree. After that you should run <tt>make</tt> for
|
||||
compilation and <tt>make install</tt> (as root) for installation of
|
||||
<tt>nss-myhostname</tt>.</p>
